Right- I agree w/ Tom and Andres on this part also.

What are the 'competing approaches' you're alluding to here? Sending
text-format json across as we do today? Is there something else you're

I'm having a hard time seeing what else would actually have the
flexibility that JSON does without being clearly worse (xml?).
